Does this come with the aquarium mount?

This fish feeder comes with a mounting kit and brackets.

Can this feeder dispense goldfish Flakes, not pellets? Thank you.
Answer by ChewyMar 06, 2023
The Fish Mate P21 will work with flake food, however if placed in the feeder in an area with high heat and humidity there could be clumping and clogging issues.

FishMate usefulness

I have a small pond with four gold fish. I'm often traveling and not able to feed them daily. This product works great. It quickly mounted to a stand and easily comes on and off for filling. I'm very pleased with the product. It came well protected for shipping and arrived faster than expected. Because of FishMate, I no longer worry about my fish dying for lack of food. I recommend this product for anyone looking for automatic feeding. It works!

This does not hold much food

It's billed as being capable of dispensing "up to 22" feedings; this works only if each feeding is very small. I plan to return mine as it is would only cover 2-3 days' worth of summer feedings in my medium-sized koi pond. It's probably OK for other folks but not for my requirements

Automatic fish feeder

I bought this to feed the fish in our pond when we go on vacations. I have it dispensing floating Koi sticks but I wish it held more food. Our trips are usually about 10 or 12 days and I'm not sure if the food will last that long. I am currently monitoring it to see how long it lasts. There is a setting for the amount of food inside and on a 1 to 40 I have it set at about 32 to dispense the proper amount of food. The product description says it will dispense up to 21 days but it would have to be set very low in order to meet that. Otherwise it seems to work well and it was reasonably priced at $42.50

Great for vacation

This is a simple once a day feeder. No fancy frills or difficult programming simply fill the drum set the time and once a day the drum completes a turn and drops food. It is basically a clock attached to the drum

Life of a feeder.

This has been a life saving item to have. We have a fishpond at our summer home and cannot be there all the time. Being able to set this fish feeder up keeps the fish happy until we can get back. I do wish the feeder wheel that turns could be lifted out to clean underneath. No matter how hard you try not to let food get under it, it happens. This kill the life of the feeder drastically.

Love this and works great

I was surprised to see the reviews saying it didn’t work. I just ordered my second one. The first one fell in the pond and it was hours before I noticed. There is a small start switch that is visible when you install the battery. Make sure it is in start position.
